I suspect All of the above. Info suggests that the 146 fleet are pretty p1ssed off at the moment so expect more of the same. Resignations tend to go in on the last day of the month due to their 3 months plus the rest of the month policy. The management thought they would get extra warning of impending resignations but the pilots saw through that one, so they still only get the 3 months notice. Most other companys these days seem to taylor courses to suit.
